Abstract:

The essential oil of Helianthus annuus head which harvested in autumn was extracted by water-steam distillation, and it's components was characterized by gas chromatography-mass spectrometry(GC-MS). The in vitro antioxidant activities of essential oil were studied by 2, 2-di(4-tert-octylphenyl)-1-picrylhydrazyl(DPPH) and 2, 2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) radical scavenging assay. The GC-MS analysis showed 49 kinds of chemical components(comprising 91.16% of the essential oil) were identified from the essential oil of H. annuus head, and α-pinene(28.22%), limonene(6.55%), α-humulene(4.99%), trans-β-farnesene (3.58%) and camphene (3.39%) were the main ingredients. The essential oil had some in vitro antioxidant activity, and the half effective concentration(EC50) of the essential oil against DPPH and ABTS radical were 0.47 and 0.30 g/L, respectively, which significantly higher than that of BHT(8.21 and 6.16 mg/L).

Key words: Helianthus annuus L., essential oil, chemical composition, antioxidant activity
